First of all: It doesn’t matter. Legal limits must be complied with. Whether you like it or not. Where would we end up if everyone could decide for themselves whether laws apply or not?
Secondly: At least in Germany, this can happen and will be very expensive. The Federal Network Agency is on its toes and also comes by quickly if a neighbor or similar reports interference in the frequency band. I have experienced this myself.
Exactly, once they release the RC version or a new beta it will fixed I guess.
My Beryl AX is transmitting at 20dBm and on the new beta 4.6 it can be set to 24dBm on 5GHz
When someone sets the rule, I’ll follow the rule.
Rules exist for some reason, which can be for a technical or health reasons.
This is a basic thing to respect when living in a community.
I tried the signal strength on my backyard and I can tell it is just a little bit better compared to my TP-Link, I can safely say the Flint 2 range could be better, sometimes I got 2 bars on my phone on this same spot, but that was very hard to see, and surprisingly the phone that was connected to the TP-Link network also got 2 bars a few times, in terms of dBm the signal is always higher, but just a little bit. Yesterday I saw a huge difference having the router less than a meter away so I guess the 4 antennas play a big role here. It’s hard to measure but I don’t think it is transmitting at 1000mW like it shows on luCI, I would say 22-24dBm. Who knows. The TP-Link is transmitting at 20dBm, I will leave some pictures here.
purely the dbm checking does not solve the range issues perse 
On 4.5.7 its fine if i ignore the speeds, also on my tests, but if i did this on 4.5.6 or lower there was no correctly handshaking or the internet times out, hence the dbm reporting a little better range, though also the dbm is affected on the lower firmware but theres a huge difference still in where it is practical functional and where it is not it gave me the wrong impression it was still working on these ranges but its initially much worse than i thought.
i live in a small appartment so the kitchen is the farest away and there i found i started to get issues with kitchen wifi equipment (A philips airfryer 5000 L) it required my phone and the airfryer on wifi and both became a total nightmare to setup due to range issues , with mediatek sdk 4.5.7 that issue is gone but still not a full solution if you want new OpenWrt 
This can already severely degrade past 8 meters and around 15 meters nothing works
While 5ghz is a different story for me and not really range affected.
Of course 
The range is ok to me on v4.5.6 even though it could be better. Look at this, 6 meters away with a wall in the middle the TP-Link and the Flint 2, (both on the same spot) this shows a 8dBm advantage on Flint 2’s favor, my Beryl AX is approximately 13 meters away with no walls and obstructions at all and the signal is lower compared to the Flint 2, but a bit higher than my TP-Link
What happened then ?
Your TP-Link WR841ND is 14 years old device with only 2 antennas.
My issue was a little different: I had interference on the 2.4 GHz band - which is why Bluetooth devices started to go haywire.
Since I couldn’t figure out why, I used the Federal Network Agency’s contact form to ask if they had any ideas (there might be a radio tower or something nearby)
2 weeks later, they came by with a measurement team and analyzed all the frequency bands. Free of charge.
It turned out that there was a source of interference and this was then rectified.
My main point is that people always claim that the Federal Network Agency doesn’t take action - and that may be true if you assume that they proactively drive through the streets looking for interference. But if someone reports a malfunction, it happens rapidly.
In Germany, there are severe penalties for frequency misuse. I don’t know whether they are always imposed. But if someone reports a problem, then everything takes its course.
Nope, my model is a newer version, not the v1. TL-WR840(ES) and has 2 larger antennas. It isn’t 14 years old
Like I said, the Flint 2 could be better considering it is supposed to transmit at 30dBm and has 4 antennas
Version 7 is from 2010;
Version 10 is form 2015;
9 years old…
It has a good range
